Answer:
The estimated fixed cost element of power costs is $10,000
Step-by-step explanation:
For computing the fixed cost first we have to calculate the variable cost per unit which is shown below:
= (High power cost - low power cost) ÷ (High machine hours - low machine hours)
= ($22,000 - $15,000) ÷ (12,000 - 5,000)
= $7,000 ÷ 7,000
= $1
Now the fixed cost would be
= (High power cost) - (high machine hours × variable cost per unit)
= $22,000 - 12,000 × $1
= $22,000 - $12,000
= $10,000
